IMPROVEMENT IEN' YARN-GUIDE AND CLERER.

The Schedule referred to in these Letters Patent. and making part of thesam To all whom t't may concern:

Be it known that we, A; O. DAKIN, of Clinton, and J. D. BUTLER, ofLancaster, both in the county of Worcester, and State of Massachusetts,have invented a new and improved Yarn-Guide and Clearer; and we dohereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,making a part of this specification, in which- Figure lf-is a frontView;

Figure 2, a side view;

Figure 3, a View of movable plate A, fig. l, as decached.

Figure 4, a front view of a modified form ofthe invention Figure 5, aside View ofthe modified form; and

Figure 6, a top view of the modified form.

In the process of manufacture of yarn or thread, it is necessary atcertain stages topass it through a narrow opening, in order to clear itof lumps, or loose iibres, that may be clinging to it. This openingshould be of a width corresponding to the s ize of the yarn.VV To securethe means of varying thistwidth of opening at pleasure, to correspondwith the dierent sizesoi' yarn used, in an improved manner, is theobject of our invention.

In figs. l, 2, and 3, B represents the stem of the other part of thespooler, reel, or warper.

The thread passes between the edges a a and c c, of the plates A and O,as shown by the red lines.

These plates may be of steel, and O is riveted to -D, at c c, `while A`slides upon D,Ybetween the shoulder Z el and the edge c' c', of C, asshown.

When A is set in the desired position, it is held in place bythe screwE, which passes through a slot in it, and is screwed into D.

When E is loosened, and A is slipped up or down between l l and c c',the width of the opening between a a and c c, is increased ordiminished.

It is obvious that the angle between c c and c c", must match thatbetween a a and a a. .Now this angle may give so little variation from astraight line, that a certain movement of A, up or down, shall produce astill smaller one of widening or narrowing the space between the platesin which the threads run.

By this arrangement, we are able to adjust, with thread, because it isexaggerated, and so more'easily measured, in the upward or downwardmovement of A.

It has been customary to have A mo`ve in slides at right angles to theedges a a and c c, in which case it has been necessary to set themovable plate bythe width of the opening as directly measured.

It was also inconvenient or undesirable to Widen the clearer so much asshould be necessary to make these thread runs, instead of at a rightangle, as has been common heretofore.

It is not necessary that A should bear upon both edges c c' and (l (l,as one of these would answer if care were taken to keep A against it,when the. screw E should be tightened.

The modified form, shown be easily understood.

The yarn is shown as running up from the. other side, and the movableplate bears only on the side adjoining d' d. It is symmetrical in itsshape, so that when the thread has worn into the one edge, it can beturned over, and the edge, which before ran upon d d', be used for theyarn to bear against.

. The iixed plate C', instead of being riveted on, as

in figs. 4, 5, and 6, will in the first arrangement, is screwed on afterbeing set in position to match the inner edge of A. It can be turnedAend for end when worn by the thread.

The holes H are for wires, such as have been heretofore used to carrythe yarn in between the plates, if it shall not be dropped directly uponthese plates.

If desired, d d, in figs. l and 2, can be run furtherk up, so as to givea longer bearing-edge on the one side.

Both of the guide-plates might be moved, in adjusting the openingbetween them for the thread, if desired, instead of only one, as shown.

It is clear that there isa great variety of shapes which the inventionmay take. But without regard to particular details, We include in it thecombination of two guide-plates, one or both of which shall have amovement oblique to their edges between which the thread runs.

' We have spoken ofthe invention only as a clearer; it may also serve asa guide for the yarn, as other styles of clearers have. f

The invention is not confined to the use of any par tioular material forthe yarn.

We claim the combination of the guide-plates A and O, or theirequivalents, adjustable by a movement of one or both, oblique to theedges between which the yarn runs, substantially as and for the purposesdescribed. l
